Patent attributes
A foldable module and a corresponding device are provided. The foldable module includes a first connection part, a first pin, a first drive ring, and a first spring. The first pin passes through the first drive ring, a first pin hole which is disposed on the first connection part, and the first spring. A first convex part and a first concave part are disposed between the first drive ring and the first connection part. The first convex part is located between (a) the first spring and (b) the first concave part or the first convex part. When the first connection part rotates, or in a folding or unfolding process, the first convex part slides out of the first concave part, to provide damping force for unfolding or folding. The first connection part directly drives the first convex part and the first concave part to move correspondingly, thereby improving transmission accuracy.
